Application'led may si,

, y.; known that WILLIAM P. 15AM- he io. in the county of Passaic and 'ew Jersey, have `invented certain J' and cseinl improvements in` Tire ins. which the following is a specifin ".nracter which embodies novel feaconstruction whereby it can be end qniciriy applied vto or detached 're will operate in an eliective o preventslridding when in posin t l i ie tire.

object of theinvention is to a tire chain Whicliis comparatively ele and inexpensive in its construction, h infill not creep vartnirid the tire when 1 l? vihi n is doraiole and' e'ective in op on. sind which cannot be negligently a'p-, "o "he tire bv a careless driver Withgements of the parts as will pear as the description pro' the novel features thereof being pointed ou? in appended claims.

For full understandin@ of the invention, eierence scriptie?. vvhichzfl Figure 1 -is a side elevation of a- Wheel provided Awith a ltire having the anti-skid ding chain applied thereto. 'Fig 2 is an enlarged transverse sectional view on @he iine of Fig. l. Fig. 3 is a side elevation of a portion. of tire having a modi icetion of the tire chain applied thereto.l Fig. #i is n side elevation of a-portion of a tire sind wheei, showing -a further modificarl in which a tightening lever is employed waiving the side chainsl intooperative and accompanying drawing, in

ig. 6 is 'an enlarged detail in tightening lever. Fig. i' an view' of a portion of the?, towing the niodified 'anchoring applied thereto. Fig.l 8 is a trans- Speccatien of Letters Patent.

i, citiaen of the United States7 residing its object to provide s. devicel is to be had to the 'following de- `Patented ct. 5,- i915.; 1914. serial N5. assess.

verse sectional view through the Wheel rim showing the anchoring element clamped thereon. A Corresponding and like parte are referred to in 'the following description and ind- 6'@ cated in all the views of the drawing by the same reference characters. i

Specilically describing the present embodiment'of the invention, thennmerel l' designates a Wheel which is formed with` a rim or elly l and has a conventionalform of pneumatic tire 2 `applied thereto. Side chains 3v are' arranged upon opposite sides of the tire and are connectedby entiskid 'elements which extend Vacross theA tread of the tire. l ln the present instance these antii skid elements include plates 4 which are .transversely curved so as to'conforrn to the shape ofthe tread of the tire, the plates be- 'ing provided at opposite endsv thereof with .75 the diverging arms a vvhich are connected v by diagonal. chains 5 to the' side chains 3. These diagonal ,chains 5 have-substantially the same ldinection as the'arrns of the plates 4 and serve to retainV the plates in proper position upon the tread of theI .tire when the device is mounted'in position.

The side chains?) Menon-continuous and are'oi' such a length that gaps or-open spaces are .provided between the edsthereof. i These` spaced ends Yof `the side vcliainsJa-re connected to s rim orfellyengaging anchoring element 'which extends between e pair of the spokes of the Wheel, and the con struction is such that thetire chin can` not be mounted upon the tire-Without thens'xeo the anchoring means, as might ordinari i ,1' -be done by a careless driver. As showlx'byfli'i'g. v, 1, each ofI the sidechains 3 are ormedinj two sections and the extremities .thereofA are e5 connected by anchor chains 6 to an iichor' plate, 7 which extends around thefel'y of -the wheel. This anchor plate may be formed of'any suitable material and is-detachably connected to the side chainsso that it can 100 be placed .in position pand attached thereto after-'the side chains have' been applied to Y the tire. F or this purpose the anchor chsin's 6 are shown as perinanentlv connected to the corners of the anchor plate 7 and as pro- 105 vided with` snap hooks Spadapted to engage 'the ends'of the side chains 3. With this construction it will bev obvious, that .the tire chain will not remain in Aposition uponthe lvltire unless the anchoring plates andchairis im,

A non-skid tire chain including a side chain having a gap between the ends tbereof. a felly engaging clamp' adapted to be the pivot stud and constructed to have a de` rig ily applied to the telly between a pair of spokes, said clamp being formed with a pivot stud, a finger operated tightening lever pivotallymounted between its ends upon 7. A tire chain including side chains having gaps between the ends thereof, non-skid elements connectlng the sidehalns so as t0 extend acrosstthe tread of the tire, a elly engaging anehor member provided with verse heads of the pivot studs so that the levers can be applied to the pivot studs or removed therefrom when turned into such u position that the slots are in registry with the transverse heads, an operative comm:-

tion between the chain tightening tfwrs and the ends of the side chains, and means' for locking the chain tightening levers in operative position.

In testimony whereof I affix my signature in presence of two witnesses.
